BATTERY FILLER Filed May 18, 1928 Patented @et 14, 1930 UNITED STATES PATENT OFFICE DALPH FRY, OF ROCHESTER, PENNSYLVANIA, ASSIGNOR TO FRY EQUIPMENT CORPO- RATION, OF ROCHESTER, PENNSYLVANIA, A CORPORATION OF DELAWARE BATTERY FILLER Application filed. May 18, 1928. Serial No. 278,666.

This invention pertains to battery supply devices, and more particularly to devices for automatically dispensing fluid to storage batteries so that there will be a substantially constant supply to the control valve for the cells of said batteries.

It is usual in vehicles, or as a matter of fact any source of energy, as an engine, motor, etc., employing storage batteries current supply, to experience great diiiiculty, espeeially in Warm Weather, in keeping the fluid at the correct level in the cells of the battery.

f excess fluid is supplied to the cells, corrosion takes place around the top of the battery as a portion of the fluid leaks through the air vent in the battery cap, causing electrolytic actien to take place between adjacent metal parts, such as the steel battery supports or cover. If too little fluid is supplied to the 2o cells, there is danger of exhausting the battery, entailing charging and other costs, which are expensive. Then, too, oftentimes there may be a small leak in one of the cells of the battery which Will gradually empty the cell, causing damage to the plates, With the result that new plates must be supplied and the battery must be recharged.

It is therefore an object of this invention to provide a novel, inexpensive, simple and i positive device for keeping the cells of a storage battery supplied with the proper amount of Huid at all times.

Another object is to provide a device tor a vehicle to supply fluid to the batteries, which 3.3 device is particularly actuated when the vehicle is in motion.

Still another object is to provide a device actuated by the mot-ion of a vehicle or by articial mot-ion to supply fluid to the batteries,

the parts of the device being so arranged that the cells of the batteries will be resupplied automatically when the fluid in said cells has fallen belou7 al predetermined level.

Yet another object is to provide a device for supplying fluid to various means, said device being either manually or automatically operated.

A further object is to provide a device insuring adequate fluid supply to battery cells C3 even though there may be a small leak in said cells or regardless of the period of vibrations of the device.

A still further object is to proviee an inexpensive and effective fluid reservoir for automatically dispensing fluid therefrom and one Which fulfills all requirements of manufacture and service.

lVith these and various other objects in View, the invention may consist of certain novel features of construction and operation as will be more fully described and particularly pointed out in the specifications, drawings and claim appended hereto.

In the drawings, Which illustrate an embodiment of the device and wherein like reference characters are used to designate parts- A Figure 1 is a side elevation of a. container embodying the invention;

Figure 2 is a sectional elevation of the device illustrated in Figure 1 and Figure 3 is a top plan view of the device, the same being taken substantially in the plane as indicated by the line 3 3 of Figure 1.

In the assembly of the device, it has been '75 found desirable to provide a. container 10 of pyreX or other material which is preferably transparent and substantially unbreakable, with spaced ribs l1 so disposed as to form positioning means for a suitable band or support (not shown) for the assembly.

The col'itainer is preferably closed at the bottom and provided with a. aperture 12 vthrough which .seat nnmber 1? is adapted to extend, said seat member being preferably provided with a shouldered portion 14 spaced from the container by means of the washer 15. Member 13 is threaded as at 16, and is adapted for eiigagernent with the nut 17 disposed on the outside of the container and being r adapted to draw the shouldered portion. A into tight engagement with the Washer 15 to therebyv prevent any leakage of the iiuid around the seatmeinber. The end of the seat member is provided with a shoulder or enlargement 18 for the reception of a discharge hose leading to the valves of the battery cells,

all as particularly described in application Serial No. 201,840, filed J une 27, 1927, though it is to be understood that any other v :term otvalves may be used.

The seat `member 13 is provided with a channel 19 entending therethrough, said channel adjacent the upper ond being provided with a bushing 2O providing a valve seat for the valve member to he later described.

The container is provided with a top 21 iirovided with a threaded orrbayonet socket connection 22 therebetween, a washer 23 beinginterposed'between the top and the container to prevent any leakage therefrom. |The top is provided with a vertically adjust ed thimble 2a disposed above the member 13,

the saine having threaded connection with the top as at Q5, said thimble being provided with the channel 26 Vextending therethrough. Valve member Q7 is disposed between the valve seat 13 and top 21 and extends upwardly through aperture .26, said member consisting essentiallyA of afstem or inertia member 28, said stem being'preterably ot' a; smaller diameterthan the diameter of the channel 26 and being provided with a support 29, between which and the t-himhle 2111 there is disposed an expansionv spring normally urging the valve member 27 toward theI valve seat 13. r1`he thimble 24 serves as a guide for the stem 28 and'also as a seat for the spring 30. The valve stem 28 is provided with a depending needle valve 31 extending into the bushingQO and preferably of Vslightly smaller Y diameter than said bushing, there being pro- Vvided interlitting collar members 32 and 33 on member 27 between the valve stem Q8 and the bushing 2O of any suitable material as will arevent assae'e of fluid throuoh the i bushing when the member 33 is in Contact with said bushing.

In operation of the device, ,1t will be appreciated that moving the thimble 24 upwardly or downwardly imposesa less or greater downward pressure on the valve member l through the spring SO, thereby varying the seating capacity of said valve, Different vibrations ot the container', dependingvupon the Vdevice upon which it is mounted, will causel relative movement loit the 4valve member with respect `to the valve seat and bushing, the

same being limited by the spring 30,V such n movement causing unseating of the member 33k and permitting amounts of fluidy to flow past the valve seat, througl'i'the passage 19 Vinto the connected tube to the battery cells to thereby replenish the same with said fluidl 'Should it be desired to operate the device without imparting vibrations thereto, it is only necessary to manually litt the valve stem unseating of the valve, whereupon .any amount yof Huid may be allowed to be supplied to the batteries to be filled or repleiv ished. Y Y

lt is to beunderstood that I do not wish to be iiinitedpby the exact embodiment of the device shown, which is merely by way of il- Lvvaeee said gaine and directly past saidv seat when the valve is unseated, said valve having a rigid stem provided with a supporting member, an adjustable guide for said stemrarried by said closure and through which said stem extends outwardly of said container, and resilient means disposed between said support-ing member and Ysaid last named guide and lsur'rounding saidstem for vadjustably controlling the operation of said valve.
